<p>PROBLEM TO BE SOLVED: To provide a device for measuring the quality of packet communication, that can measure network performance at a packet level with high accuracy by utilizing extracted data consisting of conventional packets, in the case of packet communication bridging different networks adopting a different address system. SOLUTION: The device for measuring quality of packet communication acquires an address conversion table, conducts inverse conversion address information of data extracted by a packet observation means according to conversion rules in the table, identifies same packets by using header information for a key, when the address conversion is finished, and utilizes a time stamp and the header information to calculate quality information.</p> |
